## Statistics

- For reviewing statistics concepts, past students have recommended video lessons from Khan Academy and Brandon Foltz (which has ads), especially for reviewing distributions, hypothesis testing, and type I and type II error.
- Explained Visually: a website that visualizes some concepts from class (markov, conditional probability, eigenvectors, etc.)
- Where did the Gaussian (normal) distribution come from? see Stahl, 1996 article in Canvas site Readings folder
- 1-sided vs 2-sided tests for a change in the variance: NIST Engineering Statistics Handbook, Chi-Square Test for the Variance (If you're using a 2-sided test, you need to look up alpha/2 in the chi-squared tables, as shown on the link.)

## Programming

- PythonNumericalDemos demos and visualizations such as this Interactive Correlation Coefficient Demonstration, by Michael Pyrcz (University of Texas at Austin)
- Earth Data Science - EarthLab tutorials: time series data, data exploraiton and analysis
- Managing conda environments
- The Unix Shell

The UW eScience institute offers data science office hours which could be useful for your projects or your own research work.
